The PD685 is an easy to use, loop-powered indicator, certified by CSA, ATEX and IECEx as intrinsically safe. The PD685 carries international certifications under both the Class/Division System and Zone System, and is thereby suitable for use in gas and dust hazardous areas worldwide. For Division 2 applications where intrinsically safe interfaces are not needed, the PD685 is able to be installed without barriers! To achieve this ability, the PD685 underwent a special 'nonarcing assessment' under the UL 121201 and CSA C22.2 No. 213 standards, and was determined to be a device incapable of causing an ignition on its own. The PD685 is wellsuited for both indoor and outdoor applications and carries a variety of environmental ratings, including NEMA 4, Type 4X and IP67.

The PD685 can be seen from considerable distance in bright sunlight or dimly lit areas when the standard backlight feature is activated. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meter gets all of the power it needs from the 4-20 mA loop and its 1 V (4 V with backlight) drop results in a minimal burden on the loop. The meter features a wide -40 to 75°C operating temperature range and is available with a ½" conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.

The PD650 is a large display, analog input process meter with flow rate/totalizer and batch control capabilities housed in a rugged, die-cast aluminum, NEMA 4X enclosure. It accepts the common process signals such as 4-20 mA, 0-5 VDC, 1-5 VDC and 0-10 VDC and displays these signals in engineering units on a 2.3" (58.42 mm) large, high efficiency, 4 1/2 digit LED display. The 115/230 VAC models also provide two isolated 24 V power supplies to drive both the input and output loops. Options include up to 4 relays for alarm or batch control and an isolated 4-20 mA transmitter output.

The Vantageview PD6770 is a plastic, loop-powered process meter with 1" display digits in a field-mountable enclosure designed for demanding applications. The meter derives all of its power from the 4-20 mA loop with a small 1 V drop, so there is no need to run additional, costly power lines. The PD6770 is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. It is programmed using four easy-to-access, front-mounted control dials.

Go with the Helios PD2-6210 when you need to do batch controlling using a 4-20 mA output flowmeter. The PD2-6210's huge display means operators don't have to be close up to the instrument to monitor the status of the batching application. And its NEMA 4X enclosure allows the PD2-6210 to be mounted in wet, dusty, and dirty areas. The PD2-6210 can handle single and multi-stage batching applications.
